KENNEDY SPACE CENTER, FLA. - Out for a stroll on a sunny Florida day, a trio of wild pigs cross the road near NASA Kennedy Space Center’s Vehicle Assembly Building, in the background. The wild pigs have flourished in the environs around KSC, which shares a border with the Merritt Island National Wildlife Refuge, without many predators other than panthers and humans. Pigs were introduced to Florida in the 1500s and are now found statewide in wooded areas close to water. Pigs are omnivores, foraging on the ground and rooting just beneath the surface, which damages the groundcover. Wild pigs eat almost anything that has nutritional value, including tubers, roots, shoots, acorns, fruits, berries, earthworms, amphibians, reptiles and rodents. Appearance is similar to domestic hogs, but leaner, with a longer, narrower head and a coarser, denser coat. Females may have two litters per year. The piglets are weaned in a few weeks but remain with the mother for several months.

CAPE CANAVERAL, Fla. -- Several adult and baby wild pigs, in a variety of colors and patterns, graze in a grassy field at NASA's Kennedy Space Center in Florida. The wild pigs have flourished in the environs around Kennedy. The center shares a boundary with the Merritt Island National Wildlife Refuge, consisting of 140,000 acres. The refuge provides a wide variety of habitats -- coastal dunes, saltwater estuaries and marshes, freshwater impoundments, scrub, pine flatwoods, and hardwood hammocks -- that provide sanctuary for more than 1,500 species of plants and animals, including about 331 species of birds.

KENNEDY SPACE CENTER, FLA. -- Near Launch Pad 39B, wild pigs (at right) root for food near a stand of trees while Space Shuttle Discovery rolls out to the pad. The 4.2-mile journey from the Vehicle Assembly Building began at 12:45 p.m. EDT. The rollout is an important step before launch of Discovery on mission STS-121 to the International Space Station. Discovery's launch is targeted for July 1 in a launch window that extends to July 19. During the 12-day mission, Discovery's crew will test new hardware and techniques to improve shuttle safety, as well as deliver supplies and make repairs to the station.
